With a pull of a trigger, farmers can tackle greasing jobs in a matter of minutes. Milwaukee Tool expands its 18v line-up with the new M18 cordless grease gun. Team FIN, a group of farmers who test products for Farm Industry News, tested the new tool to see how it performed and rated it on a scale of 1 to 5.
